Patent DE-2506282-A1 (DE)
Title: Outlet valve for vessels - having flat ended piston in vessel wall which retracts to open outlet
Inventor: TRNKA PREMYSL DIPL ING
IPC: B01J4/00
Filed: 1975-02-14
Abstract: Outlet valve for use on tanks and vessels has a piston mounted on shaft which when the valve is shut is flush with the vessel wall. The piston seals in a cylinder by a sealing ring. Lower down the cylinder are outlet ports (I) which lead into an annular chamber drained by a branch. When the piston is retracted, the valve opens by allowing liquid to drain out of (I). On the shaft of the piston is a threaded section on which a wheel is mounted. The wheel moves freely on the valve body. The seal is kept tensioned by a spring which presses against the cylinder head and a shoulder on the piston extension. A lever allows this seal to be locked in position whatever the posn. of the piston, up or down. The locking nut and seal is provided on the end of the shaft to limit the shaft movement and locate the piston flush with the vessel wall. If desired, the shaft can be connected to an actuating device, e.g. a pneumatic cylinder. Used esp. in mixers and reactors. If a conventional valve on a branch is used, there is always a dead space above the valve. This means that non-homogeneity results in mixing operations and possibly off spec. reactions in a reactor. The use of this type of valve avoids this problem.

Title: Rotary sorting machine for cylindrical magnetic components - has permanent magnets on vertical rotor plate, releasing correctly aligned cylinders
Inventor: ENGEL HORST
IPC: B65G47/14

Title: Large area windscreen wipers for car - with drivers wiper shifted into corner of windscreen during each cycle on movable pivot
Inventor: STOLZ ALBERT DIPL ING
IPC: B60S1/34
Filed: 1975-10-24
Abstract: The two wipers (13, 14) of the car windscreen are driven by a reciprocating linkage from a main crank drive (32). The driver's wiper arm (13) is mounted on a reciprocating frame (42) swung by the linkage, to periodically displace the pivot point (31) of the wiper into the upper corner (67) of the windscreen. This imparts an elliptical sweep to the wiper to clear a larger area. The wipers are parked under the front of the driver and swing into the nearside of the vehicle, in settings which block the visibility by a minimum amount. Any dirt, snow etc. left in the cetre of the windscreen by the driver's wiper is removed by the downwards sweep of the offside wiper.
Patent DE-2558393-A1 (DE)
Inventor: D AGOSTINO VINCENT F
IPC: H01M8/10
Filed: 1975-12-23
Abstract: This disclosure is directed to fluorocarbon polymers, polymeric membranes, and electrochemical cells and processes. The polymers and membranes are produced by radiation techniques to provide improved products. For example,  alpha , beta , beta -trifluorostyrene in an inert organic solvent is grafted onto an inert film, such as tetrafluoroethylene-hexafluoropropylene copolymer, by irradiation, i.e. with Co-60 gamma radiation at a dose of several Mrad. The grafted film is then sulfonated, preferably in a chlorosulfonic acid bath. The resulting film is useful as a membrane or diaphragm in various electrochemical cells such as chlor-alkali or fuel cells.

Title: Collapsible plastics container for pourable merchandise - has horizontal partitions with apertures for passage of contents
Inventor: LISSNER HANS
IPC: B65D88/16
Filed: 1976-02-10
Abstract: A platics container for shipping pourable merchandise which is charged to it thorugh an opening or valve has >=1 partition extending parallel to that wall of the container fitted with the inlet opening or valve. The partition(s) has (have) >=1 aperture allowing hte contents to pass through. The container is used for shipping and/or storing materials in bulk e.g. granulates, fertiliser. Capacity of the article is >=1 m3. It may also be used as a silo. The partitions prevent 'bulging' of the container when filled, whether partly or completely. It can therefore be handled with loading pallets as it always presents a flat base. Also, since deformation under load is minimal, such containers may be stacked side-by-side without intermediate gaps, minimising storage space.

The vessels can be in the form of hollow rails of elastomer material, and they can be detachably mounted on the tank control cubicle. The design avoids the sludge accumulating in the measuring instruments, being partic. for tanker lorries delivering heating oil.

Title: Waste heat recuperation system for water cooled engines - in which cooling water is heated by exhaust gases and used to drive generator
Inventor: HENNECKE RUDOLF
IPC: F02G5/00
Filed: 1976-04-28
Abstract: The cooling water outlet (4) from a high performance internal combustion engine is fed to a boiler (5). The exhaust pipe passes through the boiler to transfer heat to the water. The exhaust gases then pass to atmos. (8). The steam produced in the boiler is then utilised to drive a pistoned steam engine (10) which is coupled to an electric generator (12). Alternatively, a closed water circulation cycle could be used, whereby the steam from the boiler (5) is fed to a steam turbine. The turbine exhaust is then passed through a condenser and fed back to the internal combustion engine cooling system.

Title: Continuous mounting of foamed plastic strip to tubular electrodes - uses shaped rail for holding lower electrode edges and extruded strip application
Inventor: HUTHWELKER REINHARD
IPC: H01M4/76
Filed: 1976-06-23
Abstract: The foamed plastics cover strip is continuously applied to tubular electrodes of lead accumulator batteries. The electrode plates are inserted with their lower edge into a shaped rail, while a strip of foamed plastics is continuously applied from an extruder onto the plate edge entering the shaped rail. The plate carries the strip into the rail, where by foaming and deformation the space between the rail and plate edge is filled. At the plate end the plastics strip is automatically cut-off. High pressure polyethylene is pref. used as strip material. The device for this process contains a transporter for the electrode plates and the shaped rail, in front of which is located the nozzle of the plastics extruder.
